Parameter-Efficient Fine-Tuning of Large Language Models for Unit Test Generation: An Empirical Study

Relevance: This paper explores the use of parameter-efficient fine-tuning (PEFT) methods to enhance LLMs for unit test generation. It investigates the effectiveness of various PEFT techniques like LoRA, (IA)^3, and prompt tuning across different model architectures and sizes. By demonstrating that PEFT can achieve comparable performance to full fine-tuning while significantly reducing computational costs, the study suggests a more efficient and accessible approach for using LLMs to assist software developers in test automation.

Ablation is Not Enough to Emulate DPO: How Neuron Dynamics Drive Toxicity Reduction

Relevance: This paper investigates the internal mechanisms of direct preference optimization (DPO) for toxicity reduction in LLMs. It challenges the common explanation that DPO works solely by dampening toxic neurons and reveals that it involves a more complex process of balancing opposing neuron effects. By analyzing neuron activation changes and projecting them onto a toxicity probe, the study provides insights into the complex dynamics underlying DPO, contributing to a better understanding of how LLMs learn and how to improve their explainability and control.
